I have recently purchased a MAC Offroad pro-chamber and a MAC axleback system for my car and after installation I only have one concern. After the install My check engine light came on (probably the O2 sensors?) and I can smell fuel when standing outside the car which means? running a little rich or lean? I purchased the parts from brenspeed and plan on purchasing the C&L CIA with the SCT brenspeed tune...will brent be able fix the engine light and the air/fuel problem with the tune?
Other then that I love the exhaust combo... I'll have vids up eventually, it sounds so mean.
